"Smittia dentata sp. nov.

(Pl. IV, fig. 8)

Zoarium incrusting, with zooecia ovate to hexagonal, having large pores round the border, eachpore separated by a short ridge, surface smooth or slightly granular. Oral aperture large, with bidentate lyrula and a cardella at each side. Near the lower corner of the aperture, at each side there is a small, tumid avicularium with semicircular mandible. Ovicell unknown. In the general form it much resembles the Mucronella bicuspis Hincks, but differs in having a row of pores round the border, instead of the few large punctures of the New Zealand specimens. The fossil S. biincisa Waters from South Australia and Victoria is very closely allied to these two, and the Mucronella serratimargo Ortmann, from Japan has a similar aperture.
